Application med December 27, 1909. serial are. 535,171.

To all whom it may concern:

Be it known that I, HENRY LECHTENBERG, a citizen of the United States of America,

. residing at Quincy, in the cou'nty of Adams and State of Illinois, have invented certain new and useful Improvements in Crushers, of which the following is a full,.clear, and exact description, reference being had to the accompanying drawings, forming part of this specification. a

My invention relates to a crusher that'is adapted to crush and separate various kinds of material, the crusher herein shown he ingmore particularly adapted to break the coke and cinders which remain in foundry cupolas after molten metal, has been poured therefrom. When used for this purpose, the apparatus also separates the coke and particles of metal which are mixed with the cinders.

Figure I is a side elevation, partly in section. Fig. II is an end view, partly in section. Fig. III is a vertical section,- taken on line IIIIII, Fig. I. Fig.,IV is a section taken. on line IV-IV, Fig. III. Fig. V is a section taken on line V-V,- Fig. I. Fig. VI is a section taken on line VI'-VI, Fig. V. e

In the accompanying drawings :--A indicates a tank upon which standards 1 are mounted, a drum Bbeing journaled in said standards. A drive pulley 2 is connected to a shaft 3'by clutch mechanism E. This clutch mechanism forms no part of my invention and I, therefore, do not deem it necessary to show or describe the details of its construction. 1

4. indicates a pinion, (see Fig. II), secured to the shaft 3 and meshing with a gear wheel '5, the latter being fastened to the rotatable drum B.

When rotary motion is imparted to the drum B, the material contained therein is crushed by a bar 6 loosely arranged in said drum; The material to be acted on by the crusher is introduced into the drum through an opening that is normally closed byfa door 7. This door is provided with suitable locking means which form no part of the present invention.

In addition to being'crushed, the material is acted on by a constantly running stream of water forced through the drum B by-a pump F. The pump is driven by a shaft 12, provided with a pinion 13 which meshes with a bevel gear 14;, the latter being secured to the inner face and is provided with inclined I non-radial ribs 20 which constitute partitionsdividing the head into compartments and extend from points adjacent the inlet port to the flange 19. The ribs 20 are preferably integral with the flange 19 and shaped so asto form angular ockets 21 adjacent the periphery of the inlet head '0. The flange 19 and ribs 20 are coveredby a pair of semi-circular plates 22 secured to the inlet head by screws 23. The plates 22 are provided with openings 24, which register with the pockets 21 and allow water -to pass from the inlet opening 18 to the interior of the drum B.

Prior to this invention, crushers have been provided with a hollow inlet head and a perforated plate forming the inner wall of said head. These perforated plates allow the water to take the path of least resistance and thereby enter the drum at a point above the crushed material. The structure herein shown causes the water to be discharged only into thelower portion of the drum where the crushed material is located.

The discharge head D is provided with an annular flange 19, inclined non-radial ribs 20 which constitute partitions dividing the head into compartments, angular pockets 21, and cover plates 22, having openings 2r which register with said pockets.

The water passes into the hollow head D through openings 24= and is discharged therefrom through an opening 25 in a trunnion 26.

When this apparatus is used to crushoinders with which coke and particles of metal are mixed, its action; is as follows: The drum revolves in the direction indicated by the arrows in Figs. III and V, and the material is crushed by the bar 6. Some of the heavy material enters the pockets in the inlet head and is carried by said pockets to a point above the main body of material. These pockets have inclined walls which cause their contents to be discharged by,

gravity at a point above the water level. Coke and cinders entering the inlet head tend to rise to the water vel, but are pre- -vented from doing so by t e ockets 21 and ribs 20. It will be seenthit i ht material entering the head at M or" N, ig. III, is prevented from rising and retained in the pockets by the ribs 20. At 0 the light material is freeto rise, but, asathe drum revolves, this material 'is pickedu by an-inclined rib and discharged-into t e drum at P or Q. At the-discharge end of the drum,

the coke and cinders which enter the pockets 21' are free to rise at S and float toward the dischar opening 25. If any of thislight materia is carried in the pockets toa oint above the water level, it is dischar ed t erefrom at T and is moved towar the discharge opening 25 by the inclined ribs. It will now beunderstood that the coke and cylin er and falls into a receptacle 29. The p out through articles of metal which are scooped up y the pockets of the dischar e head D are or V. H0w-.

discharged into the drum at ever, if, any of these heavy particles should remain in the pockets and pass to the point indicated by T, they will simply fall and be 'again scooped up by 'thepockets during a later. revolution of comprising an outer wall provided with an inlet opening, an inner wall having discharge openings, ribs extending from each discharge opening to a point adjacent tothe inlet opening, each of said ribs being sub stantially L-shape at the discharge opening to form a' pocket for receiving material passing into the head, said ribs being inclined to serve as guides for deflecting the material in said head and causing it to pass the dischar e o enings.
